Best Cable Modem
Our Selection
Motorola MB7621 The most popular modem. Compatibility with most ISPs. Mobile internet connections up to 600 Mbps are possible using the Motorola MB7621. It has an eight-month warranty that is valid for two years and is easily supported.
Amazon: $90 From Walmart; $90 at Walmart. Best Buy: $80
The Motorola MB7621 supports high internet speed and reliability. It is compatible with almost every US cable internet provider, including Comcast Xfinity and Spectrum. Because it is a DOCSIS3.0 modem, the MB7621 can support plans of up to 600 megabits each second. It also has 24 downstream channels as well as eight upstream channels. It also includes a two-year warranty.
Buying Options
$160* from Amazon $150 from Walmart $169 from Staples *At the time of publishing, the price was $150.
The Motorola MB8600 modem is best for gigabit internet plans that allow you to purchase your own modem. It’s also affordable and comes with a two-year warranty. To guarantee gigabit speed from cable ISPs you will need a DOCSIS 3.1 Modem. The MB8600 can also be used with gigabit internet via networks using the DOCSIS 3.0 standard. Sparklight/Cable One, for instance, supports both DOCSIS 3.1 (32×8) modems and DOCSIS 3.1 modems to its GigaOne service.
Do not buy a gigabit-speed modem unless your ISP has gigabit service. The additional expense for DOCSIS 3.1modems will not pay off until you get one of these more expensive plans. Also, your ISP might offer gigabit service over fibre rather than cable. You may be unable to bring your own modem if they offer gigabit services.

Arris
It’s unlikely that the best modem for your cable internet service is something you are thinking about every day, but it’s worth considering the next time you pay your monthly bill. By purchasing your own cable modem, instead of renting equipment from your provider’s drop-off location, you will save money on internet services.
Although equipment rental charges may seem absurd, they are not a joke. Some ISPs can charge up to $14 per monthly for the use of one their modems. That cost could also increase over time. You’ll be able to pay for the cost of a cable modem with a half-year-long lower internet bill. From that point forward, the money you would dole out to your internet provider to rent a usually aging modem stays in your pocket.
What speed internet connection do you need? We’ve compiled a list of the top-rated cable modems. It doesn’t matter what modem you choose, make sure it’s compatible to your ISP. Also ensure that the device delivers speed in accordance with your service plan.
What Cable Modem Is Best?
Motorola MB7420 is the ideal cable modem for most people. This modem works with all internet providers (including Spectrum, Cox, Comcast) and delivers high speeds for most people (anyone who has an internet plan that exceeds 300 Mbps). Its two-year warranty is twice as long as the warranty for the Netgear CM500, which also performed reliably in our tests. The CM500 often costs less than the MB7420 so it is a worthwhile alternative for bargain hunters.
Netgear’s CM600 can be a good choice if you have internet speeds greater than 300 Mbps. It is also more reliable than high-speed competitors.
The best Black Friday deals on cable modems rarely include modems, however that does not mean you won’t have to spend full price if your modem is purchased in the holidays. Many of our top-rated cable modems have seen price drops, so make sure you shop around to find the lowest price.

What to Avoid
We once voted the Arris Surfboard S6183 as our best modem. Its solid performance will please most internet users who do not pay high-speed services. However, this modem is becoming harder to find. Best Buy sells the SB6183 as of writing. If you can track down the SB6183 at a competitive price, its two-year warranty also is a big plus.
All-white SB6183 is small at 5.2 x 5. x 2.21 inches. It can be placed next to your router, cable box, or other hardware that you may have. I find the coaxial cable connector a little close to the power connector. However, this will likely be an issue when you set up your modem.
The SB6183 uses a series of small vertical indicator lights. It is very simple and easy to spot. Yellow lighting might be hard to spot in direct sunshine. You can still glance at the SB6183 to determine if there is an issue with your internet connectivity.
Best Cable Modem Vs. Best Router
Modem-router combos seem to be preferred by manufacturers of home networking equipment over single cable modems. The hybrid network devices are more versatile than separate routers and modems, which makes it appealing to consider buying one. But, modem/router combos are not recommended.
First of all, a brief background. As our modem-vs. router comparison shows, these two devices have very distinct purposes. Cable modems provide internet connectivity in your home, while routers wirelessly distribute the internet connection to all of your smart-home devices, including phones and tablets. It’s not a modem that will make your internet connection reachable. You need a router.
It’s not a good idea to have the networking devices separated. You can lose both your modem and router if any of the components in a mixed device fail. Because routers are able to support new features faster, it’s easier to update individual devices. As you can see, modems are slower to evolve.

What We Do to Test the Best Cable Modems
Comcast Performance Pro Home Internet Service tests every modem. Once we have run speed tests to verify that modems can deliver their download speeds, our regular networking setup uses the modems to test reliability.
Every modem we test is hooked up in the reviewer’s house. We then use it to set up our networking system. It allows us both to check a modem’s compatibility, and also to assess its reliability. We also track retail websites for the lowest prices on modems that we have tested.
Image credit: Tom’s Book. In order to verify that the indicator lights are clearly visible on the modems we use them in homes with many connected devices (laptops, tablets, etc.). We evaluate how easy modem setup is. Since the principal reason for purchasing a cablemodem is to avoid monthly rental fees from ISPs for modems that are not yours, we also weigh how long a modem’s warranty.
